The new MacBook Pro doesn't seem to be that big of deal any more.

evilson How pure is the beer in Germany?

From the top of my head, polyvinylpyrrolidone, lactic acid, bentonite and gypsum are on the permitted list. For beers brewed with top fermenting yeast, sugars and artificial sweeteners are permitted as well (I think they do need to be listed, though).

Note that all of these are used by brewers intentionally, not just as a side-effect. They are used to clarify or to make water more suitable for brewing.

evilson How pure is the beer in Germany?

A very misleading and poorly researched article. There are dozens of additives and agents allowed in brewing in Germany, but merely because they don't have to be listed on the label, breweries can uphold the illusion of purity.

It is well worth the money. I still have my first edition copy on my desk, the second edition on my nightstand and the money ready for the third edition. It easily replaces several other, pricey books.

"Investigation using large-scale studies is thus needed."

Which would be the conclusion of pretty much any result that they could have had. I could have given you that recommendation even without conducting a study at all.

evilson Habits of cell phone usage and sperm quality

If I interpret the abstract correctly, the change in sperm they observed was only correlated to talking on a cell phone whilst charging it (that is, holding it next to your head), where keeping it right next to the groin did not show any significant influence?

That doesn't sound like a plausible outcome of radiation having any influence.

evilson Habits of cell phone usage and sperm quality

Fertility decreases with age, especially in women. That your second child took longer to conceive than the first is no evidence of anything and even less of the influence of cell phone ownership. You might just as well claim that having your first child decreased your fertility, or anything else that happened to you in between. (Bought a new car? A new TV? Different brand toothpaste?)

evilson Ask HN: How are some people exceptionally productive?

Not wasting time on HN helps a lot. My productive days are those where I'm very focussed and not distracted.

As a scientist, shouldn't he be all about trying to understand things as opposed to dismissing them outright?
